My 5in1 stopped updateing on dashboard.

My 5in1 stopped updateing on dashboard. It continues to work on the main display that came with it. Trying to figure out what is happening I deleted the 5in1 from the dashboard. Now I can not get it back. When I go to "devices" onthe dashboard settings the 5in1 is not displayed. ??? How can I get the 5in1 back on the dashboard?
